Patent DE-4221569-A1 (DE)
IPC: E03F5/10
Filed: 1992-07-01
Abstract: Arranged in a liquid-storage area (2), e.g. a stormwater-retention tank, there is a flushing chamber (21) with a flushing opening from a siphon-type flow channel (24) which is configured such that the storage liquid located in the flushing chamber (21) is held back by atmospheric air pressure when the liquid level in the storage area (2) drops. In the top (33) of the flushing chamber (21) there is located an air-inlet (34) which can be closed by an aerating valve (35). The aerating valve (35) comprises a pressure meter with a diaphragm which deforms when subjected to compressed air and closes the air-inlet opening. A vacuum fan (36) is connected to the flushing chamber (21) by means of a suction line (37) and to the aerating valve (35) by means of a pressure line (40). By means of the vacuum fan (36), first of all the aerating valve (35) is closed, the flushing chamber (21) is, furthermore, evacuated and thus filled with flushing liquid. Actuating a solenoid valve (56) permits a pressure compensation which makes it possible for air to enter into the flushing chamber (21) and thus triggers a flushing surge. <IMAGE>

Title: Improving the extn. of polyamide granules - by counter-current extn. with an upward stream of water, with injection of nitrogen@ gas into the granule-water mixt
Inventor: KLEIM HOLGER DIPL ING
IPC: C08G69/46
Filed: 1992-09-18
Abstract: A process for improving the extn. of polyamide granules (I) by passing a countercurrent of water upwards through the granules comprises feeding nitrogen into the granule/water mixt. with a (nitrogen):(water) ratio of 0.01-25 wt.% per unit time. Pref. the nitrogen is injected in several part-streams at different points in the polyamide-water mixt. USE/ADVANTAGE - Used esp. for the purification of polyamide-6 granules by removing oligomers and monomer. Injection of nitrogen improves the extn. process by increasing turbulence, and also prevents back-mixing; the process therefore reduces the consumption of water and increases the final concn. of extract in the water without changing the residence time of (I) in the extractor; the process is also less prone to interference and therefore more user-friendly. The amt. of residual extract in the granules can be reduced to below 0.5%.
